$8700 airline charge dividing the internet

A furious uncle has blasted Delta for not offering his family cheaper flights home after his young nephew broke his leg in Thailand.

Tyler Davis, from the US state of Washington, wrote a series of messages on Twitter about the issue that's divided the internet.

Tyler's nephew broke his leg in Thailand after he was hit by a motorbike, The Sun reported.

According to a series of tweets, Mr Davis' brother wanted to fly home early with his son for treatment with a paediatric orthopaedic surgeon and requested business-class seats so the boy could keep his leg elevated in a bid to avoid blood clots.

Mr Davis accused Delta of leaving them abroad as they were unable to offer the father and son business-class seats on a flight for less than $8700 for both seats.
